Mudflap provides a better value for diesel fuel without any real complications to use and without targeted market ads. All the information you need to complete your fuel and/or DEF purchases is provided when get your fuel code. It even tells you if you need a separate code each for fuel and DEF. I recommend trying it. Your purchase receipt summaries are emailed and texted to you, often before pulling away from the pump.

Last time I used mudflap I did not get the discount. I drive a car and used the auto diesel pump at Sapp Brothers so I am not sure if that is the reason or not. It seems like there is an effort to just type in the fuel code at the pump but that did not work. I still had to go into the store. I think this would be a smoother process and the employee will not have to search around for their ipad. Other than the last time my experience has been great except for one time at Caseys in Norton Kansas.

Hi Gary, thanks for sharing your feedback. Credit card payments come with higher processing costs, and the 1.9% fee helps offset a portion of those expenses. This allows us to continue offering credit cards as a payment option for drivers who prefer them. Mudflap still covers most of the processing cost to keep the fee as low as possible. If you'd rather avoid it altogether, you can switch to a debit card or bank account in the app, or call us at 1-888-885-3835 and we’ll be happy to help.
